How WN4210 actually runs

Pro Flight Search has tracked every published board update for WN4210 across the SJC and AUS boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~69 min) but landed noticeably late (~43 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how WN4210 operates rather than what the timetable promises. Numbers refresh as new flights operate.
